Energy is a critical resource parameter in wireless sensor networks. This paper presents an overview on one of the existing energy efficient routing protocols which satisfies the criteria of QoS (Quality of Service) parameters. Redundant data can decrease communication costs and energy consumption. Since energy conservation is a key issue case, redundant data can be aggregated at decreasing communication costs and energy called DRINA that has some key aspects such overlapping routes, high aggregation rate, extensively compared to two other known solutions.
